Lifting heavy objects

Plugging and unplugging boards

Do not stand or walk under the heavy objects that are being lifted.
 Only trained and qualified personnel are allowed to lift heavy objects.
 Before lifting, check whether the required tools are complete and
intact.
 Before lifting, ensure that the lifting tools are firmly fixed on a wall
or fixtures with enough load-bearing capacity.
 Use simple and short commands to avoid accidents and damage to
humans or materials.
 While lifting, ensure that the angle between two ropes is no larger
than 90°.
When inserting a board, wear an antistatic wrist strap and antistatic gloves. Insert
the board gently to avoid distorting pins on the backplane.
Place the board along the guide rails.

 To avoid short-circuits and scratches, be sure boards do not touch
other boards.
